>>13875608>Every type has several good pokemonThat's debatable. Ice was shit for a while and still is with maybe Cloyster and Mamoswine ares the only usable one in the lot, and that's mostly thanks to the Water and Ground typings attached. Poison is only usable if it's paired with something else. Psychic had Alakazam but now you don't see many unless they also have a Water typing.
Not all types are created equal. The one positive I do see for Fairy types is that if we look back to the last time new types were added, we got some game breakers (for the time).
Foretress, Scizor, Tyranitar, and Umbreon made up 4 of the 7 pokes with Steel or Dark typing at the time. Sneasel and Steelix were also added and more used in Gen 2's meta, leaving us with Magnemite/Magneton, Houndour/Houndoom, and Honchcrow as the lesser used/non-impactful additions.
This suggests that when GF adds in new types, they'll have a fore-runner with game-changing potential, a few with niche rolls, and about half or so will be mediocre or worse.
Of course, this is all "MUH PATTERNS!!!", but it's the best thing we've got to go off of until the game comes out. Assuming that Fairies have a similar effect on Dragons as Dark and Steel had on Psychics, Dragons will still get some competitive play but will relinquish some of their utter dominance, a single Fairy type (likely a pseudo-legendary) will become a standard on most teams in OU, and some of the abused types will have an opportunity to come back into competitive play. (Consider the change in power Fighting had between Gen 1 and Gen 2, and apply a much reduced version of that to Fire and Poison).
I kind of wish Ice would have gotten some sort of advantage over Fairy, but with Steel's recent reworks, I think it'll need an advantage over the new kids to stay relevant.
What I really hope for is some fairy moves/ new abilities/ new items that will dissipate weather and/or help clear hazards.
